FIELD OF THE INVENTION

The present invention relates generally to methods of playing games,gaming devices and systems.

BACKGROUND OF THE INVENTION

Traditional slot machine play typically involves wagering on the spin ofa mechanical or video-simulated reel. No decision making is involved,other than the decision to play. No skill is involved where the outcomeof such gaming is based upon chance.

The interconnection of multiple gaming machines to facilitate a gamingsystem with progressive jackpots is in use today. Although such widearea links involve progressive jackpots, they do not take full advantageof the potential created by the interconnection of a plurality of gamingmachines. Wide area links of gaming machines typically involvetraditional computer-controlled slot machines, which, although popular,do not involve a substantial skill element. Furthermore, traditionalslot machines facilitate a limited persistence of play. After any givenspin, a player is likely to leave the computer-controlled slot machine,because each spin is a completed cycle rather than part of an ongoinggame. A game in which each spin or turn is a part of an ongoing gamewould be advantageous because such a system would encourage a player tocontinue playing in order to complete a game in progress.

Additionally, traditional slot machine play is a solitary activity.Players compete only against the house, in an introverted process inwhich they interact not with each other, but only with the gamingmachines. With the advent of wide area links of gaming machines, atremendous potential exists to facilitate multiple player tournaments,in which players would not only compete for the same progressivejackpots, but actually compete against each other in real time. Suchmultiple player gaming would be more socially interactive, and wouldfacilitate a fun gaming dynamic.

Also, traditional slot machines are not equipped to permit a player totake a break, and to later resume game play. If a player physicallyleaves an individual slot machine, that player may never revisit thespecific game state which the player left behind. Because players liketo take short and long term breaks for a variety of reasons, a method toallow a player to save a game state and later restore the saved gamewould be advantageous. Players would like to be able to take breaks ofany length and later resume a saved game at the same or another physicallocation.

SUMMARY OF THE INVENTION

The present invention provides apparatus and methods for playing variouscasino games. In one or more embodiments, the invention comprises a gamein which the number of potential winning combinations is reduced overtime. As the number of potential winning combinations is reduced, thepayout associated with each remaining combination winning combinationincreases. In a number of the embodiments, a set of symbols or indiciaare provided. After placing a wager, a number of the symbols from theset are displayed to a player. The player is permitted to hold one ormore of the symbols and discard the others. Symbols from the remainingset of symbols are then displayed in replacement of the non-heldsymbols. The final set of displayed symbols are compared topredetermined winning combinations to determine if the player is awinner. One or more of the symbols are then removed from the set ofsymbols before the next round of play.

In one embodiment, the combinations comprise combinations achievableusing the sides of dice (e.g., all dice showing the same indicia orsymbols, the dice showing a full house, straight or the like). In one ormore embodiments, the invention comprises a game in which the number ofpotential winning combinations is reduced as play persists by removingpayable indicia based on previous pay by the player. In a number ofembodiments, such comprises removing from play face(s) of the dice, byremoving the symbols therefrom, replacing them with other symbols or thelike.

One game in accordance with the present invention is designated hereinby the term Check. In the game of Check, a player spins (rolls) fivesimulated dice to obtain certain scoring combinations during each turn.Each turn lasts from one to three spins. After the first spin, a playermay end the turn or spin again. If a player spins again, the player mayre-spin all of the dice, or hold any number of the dice and re-spin theothers. After a maximum of three spins in this manner, the turn ends.Once a turn is over, the player must assign the result of the dice toone of a number of categories on a scorecard. If the result of the dicedoes not fit any of the categories, the player must assign a zero to oneof the categories. Over the course of multiple turns, the playerattempts to fill out the multiple predefined categories on thescorecard. The game is over when the player has filled all of thepredefined categories and the resulting point values are accumulated.

The game of Check involves a substantial skill element. During thecourse of a game, a player must make various decisions, for example,whether to assign an existing score to a category or to roll again,which dice to roll again and which dice to hold, and to which categoryto assign a score. The outcome of the game and the amount of a player'swinnings or losses are directly dependent upon the decisions the playermakes.

Another such game is denoted herein by the term Z Sixty Six. In the gameof Z Sixty Six, a player spins (rolls) six simulated dice to obtainthree, four, five, and six of a kind. A player must achieve a minimum ofthree of a kind in order to begin a game.

Each turn of a game lasts from one to three spins. During the first spinof a turn, a player spins all six dice, attempting to achieve aresulting combination in which at least three of the dice are of thesame numerical value. After the first spin of a turn, the numberdisplayed by the largest plurality of the dice automatically becomes atarget number for the current turn. The dice displaying the targetnumber are automatically held, and if at least three dice displaying thetarget number have been generated, points are assigned to a score areaassociated with the target number.

After the first spin, the player re-spins the dice that were not held,attempting to generate more dice displaying the target number. Wheremore dice displaying the target number are generated, a predeterminednumber of points is added to the appropriate scoring category, and theadditional scoring dice are held. After a maximum of three spins total,the turn ends. Over the course of multiple turns, the player attempts tofill out the multiple predefined, scoring categories. The game is overwhen the player has filled all of the predefined categories.

Another such game is a game called Z Hot Dice. In accordance with thisgame, a player is permitted to spin six simulated dice. It is the goalof the player to achieve the maximum number of each of the six symbolsone through six via two-spin or roll rounds. After a first spin, theplayer selects a target number. The target number is a number displayedby one of the dice (or none, as the case may be) which has not alreadybeen played. The player holds the dice displaying the target number. Theplayer then spins the non-held dice, resulting in a final combination ofsix dice. The total number of dice displaying the target number is thendetermined. If the player receives a sufficiently high number of dicedisplaying the target number, the player is awarded a winning amount.The player is permitted to continue playing until each target number hasbeen played. After each target number has been displayed, that targetnumber is removed from the simulated dice, reducing the total remainingnumbers capable of being displayed.

The total award to the player for each target number is summed andcompared against a qualifying score. The qualifying score comprises ascore above which the player would be entitled to participate in ajackpot if the jackpot were then awarded.

A variety of options and other forms of play of the game of Z Hot Diceare disclosed.

Another such game is called Z Jackpot Dice. In accordance with thisgame, a player is permitted to spin five reels each capable ofdisplaying each of the six symbols of a dice, and three other symbols.In one embodiment, the other symbols comprise three letters in thecolors red, white and blue, with the letters being B, O, N, U and S.

In similar fashion to the game of Z Hot Dice, the player attempts toreceive predetermined combinations of target numbers, the target numbersselected from the dice symbols of one through six. A pay table isprovided for each winning combination of the target numbers. Inaddition, a bonus amount is associated with each target number.

In the course of play, the player spins the reels. If the player obtainsa combination of the letters (i.e. non-target symbols), then the playeris awarded the bonus amount. If the letters are not of the same color,then the player is awarded the bonus for the bonus associated with thenext as yet to be played target number. If the letters are of the samecolor, then the player is awarded the bonus for all of the targetnumbers. If the spin results in a combination of the letters only, thenthe player is permitted to thereafter spin again to play a targetnumber.

After the first spin (or the second spin, if the first resulted in a winbased on letters only), then the player is permitted to select a targetnumber and hold the reels displaying the target number. The player isthen permitted to spin the non-held reels. Thereafter, it is determinedif the player has received a winning combination of the target number.In one embodiment, the player must receive at least 3 of the targetnumber to obtain a winning.

Winnings for each target number and any bonus winnings are added andcompared against a qualifying score for determining if the player ispresently permitted to participate in a jackpot award. The player ispermitted to continue playing until the player has played all of thetarget numbers. At the conclusion of the game (whether terminated by theplayer or by completion of all target numbers), the player is providedwith a ticket in the event the player's score is sufficiently high toqualify for jackpot participation.

In all games, the player inserts coins or utilizes another form ofpayment/credit to play the game. The player is paid a payout dependentupon receiving predetermined combinations of elements or categories, andthe number of rolls needed to achieve the scoring dice combinations.Bonuses may be paid for successfully completing the scorecard.

Furthermore, the games directly facilitate persistence of play. Eachspin is part of an ongoing game. A player is encouraged to continueplaying to complete turns and games in order to maximize the resultingpoint values or scores accumulated on the scorecard.

Another game in accordance with the invention is referred to herein asDraw Dice. In accordance with an embodiment of this game, a method ofgame play comprises the steps of placing a wager, displaying at leasttwo indicia selected from a group of indicia, the group of indiciaincluding at least two indicia representing a side of a dice and the atleast two indicia representing a side of said dice having at least onedistinguishing attribute, holding none, one or more of the displayedindicia, displaying a replacement indicia from the group of indicia foreach displayed indicia which is not held, and determining if theresultant displayed indicia comprises predetermined winning combinationof indicia, and if so, paying the player a payout. In one embodiment,the distinguishing attribute comprises a color, such as a color of thedice. In one embodiment, the group of indicia includes each side of adice in each of three different colors, and whereby said winningcombination may include a flush of indicia of the same color.

In one embodiment, there is provided a jackpot or winning for a game inwhich the jackpot is incremented by the full amount of a wager placed bythe player to play the game. In one embodiment, the jackpot is awardedfor receiving one particular winning combination of indicia from a groupof winning combinations of indicia.

The computer-controlled slot machines may be interlinked onto a localand wide-area network with other computer-controlled slot machines. Thisfacilitates multiple player tournaments in which players compete againsteach other in real time, in contrast to playing “against the house.” Thewide area network also facilitates the payment of progressive or otherspecial jackpots. The wide-area link may have progressive jackpots orflat-rate jackpots, and these prizes may be paid daily, weekly, monthly,and/or yearly.

Player participation in the game over time may be enhanced by jackpotparticipation. A jackpot is preferably awarded at predeterminedintervals, such as every week. In one or more embodiments of a game, ifthe player has obtained a qualifying score, the player is automaticallypermitted to participate in the jackpot. In a preferred embodiment, theplayer's having the highest scores (such as the twenty highest scores)at the time the jackpot is awarded are permitted to participate. In thisarrangement, a player need not win a predetermined combination ofsymbols or the like to participate in the jackpot. All that is requiredis that, over the course of game play, the player receive a sufficientlyhigh score as compared to other players. How high of a score isnecessary to qualify changes during each jackpot interval.

The present invention also comprises a method by which a player may saveand restore games in progress. A player may save a game onto a magneticcard, bar coded voucher, or other machine-readable medium. The playermay later resume the saved game by inserting the machine-readable mediuminto any similar computer-controlled slot machine, either at the samelocation, or elsewhere on the wide area network. The computer-controlledslot machine is then initialized to the conditions and states determinedby the saved game information from the machine-readable medium, and theplayer may resume the game from where previously terminated.

One or more embodiments of the invention comprise a method of playing amulti-player game and a system for presenting such a game. In oneembodiment, the invention comprises a method in which two or moreplayers play a game, the game having the possibility of a differentoutcome to each player, and the game having a plurality of steps, one ormore of which affect the outcome of the game to each player. In oneembodiment, the method includes the step of indicating informationregarding times by which each of the steps of the game must be completedby each of the players. If a player completes a game step within therequired time, then the player is allowed to continue playing the game.If not, the player is not permitted to continue playing the game. Oncethe steps of the game are completed by one or more of the players withinthe allotted times, the winner of the game is determined by comparingthe outcomes of completed games.

In one or more embodiments, the multi-player game comprises a game of ZHot Dice or other dice game of the invention. In such an arrangement,each player may be required to place a bet or ante within a time periodor by a time certain in order to continue to play the game. If the betis placed, then each completing player may be required to spin the dicewithin a given time, and then hold none, one or more of the dice inanother time period, and so on. The player attempts to gain the highestscore possible from a combination of dice. The outcome of the game isdetermined by comparing the total scores of the players of the game.

In one embodiment, a touch-sensitive translatebutton 565 allows a player to select a language to be used for displayoutput. Of course, the various buttons or control inputs, for example551, 553, 557, and 559 described herein as touch-sensitive areas on thedisplay 115, may also be provided as mechanical electrical inputdevices, as desired.

FIG. 6 illustrates the computer system that facilities game play. In apreferred embodiment of the present invention for playing the game ofCheck, game play is facilitated by a computer program 601 executing inthe microprocessor-controlled computer 103 within thecomputer-controlled slot machine 101. In the preferred embodiment of thepresent invention, the computer program is stored on a read-only memoryintegrated circuit 603 that is operatively coupled to themicroprocessor-controlled computer 103 in the computer-controlled slotmachine 101. Of course, in alternative embodiments, the computer programmay be stored on various other storage media, such as semiconductormemory or optical or magnetic disk, or the like.

The computer program 601 executes from the random access memory 605 ofthe microprocessor-controlled computer 103 in the computer-controlledslot machine 101, and includes code 607 and data 609 to facilitate theplay of the game of Check in accordance with the game rules, as detailedbelow with respect to game play.

The computer program accepts user input from various user input devices611 of the types previously described, including coin acceptor 111, billvalidator 113, the touch-sensitive display 115, and the machine-readablemedium reading and writing device 129. Other input devices includingmechanical button type switches and lever-arm switch actuators may beused in alternative embodiments as desired.

The computer program also controls computer operation of the variousoutput devices 613 such as the display 115, the sound speaker 117, atower light 119, the meter 121, the coin hopper 123, the ticket printer125, and the machine-readable medium reading and writing device 129.

Preferably, the computer program 601 also controls communication withthe microprocessor-controlled server computer 303 which controls thelocal area computer network 301. The computer program 601 controls thiscommunication via a network port 615 and network connectivity circuitry617 contained within the microprocessor-controlled computer 103.

The computer program 601 utilizes a random number generator 619 toproduce random numbers that represent the results of the simulatedrolling of the simulated dice 541. The computer program 601 utilizesanimation circuitry 621 to produce the simulation of dice on the display115.

FIG. 7 is a flowchart, illustrating play of the game of Check accordingto one embodiment of the present invention. The object of the game is to‘spin’ the simulated dice 541 for scoring combinations, and to get thehighest total score accumulated within scoring categories of possibledice combinations. A player begins by inserting 701 one or more coinsinto the coin acceptor 111, by inserting 701 one or more bills into thebill validator 113, or by utilizing credits. The player then presses 703the touch-sensitive start game button 553 to begin game play. The playerthen selects 705 the number of credits to wager on the spin of thesimulated dice 541 by utilizing the touch-sensitive wager button 555which controls the selection of the number of credits to be wagered. Theplayer next spins 707 the simulated dice 541 by pressing thetouch-sensitive spin button 549. The computer program 601 utilizes therandom number generator 619 to produce random numbers that represent theresults of the simulated roll of the simulated dice 541.

On each turn, the player may spin 707 the simulated dice 541 up to threetimes in order to get the highest scoring combination for one ofthirteen scoring categories. The thirteen scoring categories areillustrated by the following Table 1: How the Dice Score Upper Portionof Scorecard One (or Aces) Total of dice showing One only Twos (orDeuces) Total of dice showing Two only Threes Total of dice showingThree only Fours Total of dice showing Four only Fives Total of diceshowing Five only Sixes Total of dice showing Six only Bottom Portion ofScorecard 3-of-a-Kind Total of all five dice 4-of-a-Kind Total of allfive dice Full House (3 of one number, 25 2 of another number Four-DiceStraight 30 Five-Dice Straight 40 5-of-a-Kind (or a Check) 50 Chance(any five dice) Total of all five dice

After each spin the player may assign 709 the value of the simulateddice 541 to one of the possible scoring categories by utilizing the dualpurpose score areas 503 of the touch-sensitive display 115. If a playerdoes so, the computer under program control senses the touched areas 503and totals the value of the simulated dice 541 and calculates anddisplays the resulting score in the dual purpose score area 503 on thetouch-sensitive display 115. The total score of the upper portion 505 ofthe scorecard 501 is displayed on the upper portion score total displayarea 520 on the touch-sensitive display 115. If the total score of theupper portion 505 of the scorecard 501 is 63 or higher, for example,then a bonus of 35 points, for example, is added to the upper portionscore. This bonus is displayed on the bonus score display area 519 onthe display 115. The total score of the lower portion 521 of thescorecard 501 is displayed on the lower portion score total display area537 on the display 115. The grand total score is calculated by addingthe upper portion and the lower portion scores together. The grand totalscore is displayed on the grand total score display area 539 on thedisplay 115.

Each scoring category can only be scored or selected once during a game.Once a category is used, it cannot be reused until the next game eitherwhen the game is over because the scorecard 501 is complete or theplayer presses the touch-sensitive reset button 551. Pressing thetouch-sensitive reset button 551 clears the entire scorecard 501 inpreparation for the start of a new game.

Instead, if the player has not yet spun 707 three times during thepresent turn, the player may elect not to assign 709 the value of thesimulated dice 541, but instead to spin 707 again. If the player electsto spin 707 again, the player may hold 711 one or more of the simulateddice 541 by pressing one or more of the associated hold button(s) 543.The player may also release 711 one or more of any held simulated dice541 by again pressing the associated hold button(s) 543. The player mayalso elect not to hold or release 711 any of the simulated dice 541. Theplayer then selects 705 the number of credits to wager on the spin ofthe simulated dice 541 by utilizing the touch-sensitive wager button555. The player next spins 707 the simulated dice 541 by pressing thetouch-sensitive spin button 549.

A turn is over after a player has spun 707 three times, or has assigned709 the value of the simulated dice 541 to one of the possible scoringcategories by utilizing the dual purpose score areas 503 of thetouch-sensitive display 115. After a player has spun 707 three times,the player must assign 709 the value of the simulated dice 541 to one ofthe possible scoring categories by utilizing the dual purpose scoreareas 503 of the touch-sensitive display 115. If the score cannot beplaced into one of the categories because it does not correspond orqualify, then the player must utilize the dual purpose score areas 503of the touch-sensitive display to assign 709 a zero to one of theremaining categories.

If the player has achieved a scoring combination and assigns 709 it toone of the scoring categories, the player is paid 713 via the coinhopper 123. Alternatively, the player may elect to receive credits. Thecomputer program 601 calculates payment according to a paytable, whichis based upon points scored per turn, and the number of spins needed toachieve the points, as shown, for example, in the following Tables 2 and3: NUMBER OF COINS × 3 × 2 × 1 CATEGORY Spin 1 Spin 2 Spin 3 ONES TOTAL× 3 TOTAL × 2 TOTAL OF 1's TWOS TOTAL × 3 TOTAL × 2 TOTAL OF 2's THREESTOTAL × 3 TOTAL × 2 TOTAL OF 3's FOURS TOTAL × 3 TOTAL × 2 TOTAL OF 4'sFIVES TOTAL × 3 TOTAL × 2 TOTAL OF 5's SIXES TOTAL × 3 TOTAL × 2 TOTALOF 6's 3 of a Kind TOTAL × 3 TOTAL × 2 TOTAL × 1 4 of a Kind TOTAL × 3TOTAL × 2 TOTAL × 1 Full House  75  50  25 Small Straight  90  60  30Large Straight 120  80  40 Chance TOTAL × 3 TOTAL × 2 TOTAL × 1 Check150 100  50 Check Bonus 1 300 250 100 Check Bonus 2 300 200 100 CheckBonus 3 300 200 100

If the player assigns 709 a zero score to one of the categories, theplayer is not paid. Alternative embodiments may employ differentpaytables, as desired.

The player may then proceed with the next turn and continue filling thescorecard 501. To proceed with the next turn, the player utilizes thetouch-sensitive wager button 555 to select 705 the number of credits tobe wagered on the spin of the simulated dice. The player next spins 707the simulated dice 541 by pressing the touch-sensitive spin button 549and plays a turn, as described above. The game ends 715 when the playerhas filled all thirteen categories with a score or a zero or is out ofcredits to play the computer-controlled slot machine 101.

Once the game has ended, the computer program 601 evaluates the player'sscorecard 501 against other current scores to determine if a progressivejackpot will be awarded on a daily, weekly, monthly, or yearly basis. Ifthe player has a currently qualifying scorecard 501, thecomputer-controlled slot machine 101 prints 717 a voucher for the playerwith a control number and other pertinent information for laterredemption, if the scorecard 501 is a winner.

Utilizing a local area computer network 301 and a wide area computernetwork 401, multiple players may play the game of Check against oneanother instead of “against the house.” Utilizing a local area computernetwork 301, each participating player deposits money into an individualcomputer-controlled slot machine 101 for each spin. The player whoachieves the highest scorecard 501 of all of the players who areparticipating in that multiple player game on the local area computernetwork 301 wins the money deposited by the various participatingplayers (typically, minus a percentage for the house). The samemethodology can be utilized across a wide area computer network 401,allowing players at different physical locations to compete against eachother in real time.

FIG. 8 is a flowchart, illustrating play of the game of Z Sixty Sixaccording to one embodiment of the present invention. The object of thegame is to ‘spin’ the simulated dice 541 for scoring combinations, andto get the highest total score accumulated within scoring categories ofpossible dice combinations. A player begins by inserting 801 one or morecoins into the coin acceptor 111, by inserting 801 one or more billsinto the bill validator 113, or by utilizing credits. The player thenpresses 803 the touch-sensitive start game button 553 to begin gameplay. In one embodiment, three credits are automatically wagered 805 oneach spin of the simulated dice 541. In another embodiment, the playerselects the number of credits to wager on the spin of the simulated dice541 by utilizing the touch-sensitive wager button 555 which controls theselection of the number of credits to be wagered. The player next spins807 the simulated dice 541 by pressing the touch-sensitive spin button549. The computer program 601 utilizes the random number generator 619to produce random numbers that represent the results of the simulatedroll of the simulated dice 541.

The player must achieve at least three of a kind on a single spin tobegin play of an individual game. Until a spin generates at least threesimulated dice 541 displaying identical numbers, the player mustcontinue spinning 807 to attempt to generate the minimum achievementrequired for game entry. A wager is required for each spin of thesimulated dice 541. Once a spin generates at least three simulated dice541 displaying identical numbers, those simulated dice 541 areautomatically held 811, and a predetermined number of points isautomatically assigned 813 to the appropriate scoring area 503. Thenumber of points awarded is displayed in the appropriate score area 503,which preferably changes color to indicate active status. The spin thatgenerated the requisite achievement is counted as the first spin of aturn, and the scoring number becomes a target number for the remainderof the turn. A target number is a number that the player can receivepoints for generating during a given turn.

For example, if a first spin results in four aces (ones), thepredetermined number of points for achieving four of a kind on the firstspin of a first turn is automatically assigned 813 to the scoring area503 for aces 507. Aces becomes the target number for the remainder ofthe turn. Thus, on the subsequent spins of the turn, the player willreceive additional points only for generating aces.

The requirement of generating at least three of a kind applies only tothe first turn. A player must achieve three of a kind to enter the gameand begin the first turn. Once a player has generated the requisiteachievement and entered the game, subsequent turns do not require aminimum achievement to begin.

On each turn, the player may spin 807 the simulated dice 541 up to threetimes in order to get the highest scoring combination for one of sixscoring categories. The six scoring categories are illustrated by thefollowing Table 4: Score Category How the Dice Score One (or Aces) Diceshowing One only Twos (or Deuces) Dice showing Two only Threes Diceshowing Three only Fours Dice showing Four only Fives Dice showing Fiveonly Sixes Dice showing Six only

After the first spin of a turn, the number displayed by the largestplurality of the video simulated dice 541 automatically becomes thetarget number for the current turn. The simulated dice 541 of the targetnumber are automatically held 811, and the score area 503 for the targetnumber preferably changes color to indicate that it is the active scorearea 503 for the turn. If at least three dice 541 displaying the targetnumber have been generated, a predetermined number of points is assigned813 to the score area 503 for the target number.

If the first spin does not result in a largest plurality of dice 541displaying any one number, the player selects 809 a target number fromamongst those displayed by an equal number of the simulated dice 541.For example, if the first spin results in two aces, two deuces, one fourand one five, the player may select 809 acres or deuces as the targetnumber. The selection is made by touching the desired score area 503 ofthe touch-sensitive display 115. Preferably, the score areas 503 whichthe player may touch to choose a target number blink or change color orsize or otherwise provide visual indication of the choices available.

If the player has not yet spun 807 three times during the present turn,the player may spin 807 again. The player next spins 807 the simulateddice 541 by pressing the touch-sensitive spin button 549. During thesecond and third spins of a turn, any generated dice 541 displaying thetarget number are held 811. Preselected numbers of points are assigned813 to the appropriate scoring area 503 for scoring three, four, five,or six of the target number.

After each spin, if the player has achieved a scoring combination, theplayer is paid 815 via the coin hopper 123. Alternatively, the playermay elect to receive credits. The number of predetermined points awardedfor various scoring achievements is displayed in a paytable 545 on thedisplay 115. The paytable 545 is adjusted as the game progress,reflecting predetermined numbers of points to be paid for variousachievements at a particular stage of the game. For example, more pointsare awarded for achieving a six of a kind on a first spin than on athird spin. Amounts to be paid are based upon the odds of achievingvarious scoring combinations at a given stage of game play, taking intoaccount number of unheld dice to be spun, and numbers removed frompossible generation. An example of paytable 545 for a first spin of agame appears below in Table 5. NUMBER OF POINTS TO BE ACHIEVEMENT PAIDTHREE OF A KIND 3 FOUR OF A KIND 10 FIVE OF A KIND 50 SIX OF A KIND 500

Alternative embodiments may employ different paytables 545, as desired.

A turn ends 817 after a player has spun 807 three times, or achieved sixof the target number prior to the third spin.

Each scoring category can only be scored or selected once during a game.Once a category is used, it cannot be reused until the next game eitherwhen the game is over because a score has been assigned to eachcategory, or the player presses the touch-sensitive reset button 551.Pressing the touch-sensitive reset button 551 terminates the currentgame and starts a new game. Once a scoring category for a given numberhas been used, that number is replaced for the remainder of the game bya non-numerical symbol, for example the letter “Z” or a graphic symbolof a piece of fruit, or as desired. During subsequent turns, when therandom number generator 619 generates the used number, the non-numericalsymbol is displayed instead.

After completing a turn, the player may then proceed with the next turnand continue filling the score areas 503. To proceed with the next turn,the player next spins 707 the simulated dice 541 by pressing thetouch-sensitive spin button 549 and plays a turn, as described above.

The game ends 819 when the player has filled all six score areas 503with a score, or is out of credits to play the computer-controlled slotmachine 101.

FIG. 9 illustrates an embodiment of the present invention in which eachscore area 503 comprises two distinct display areas. A first displayarea 901 is utilized to display accumulation of points for theassociated scoring category. A second display area 903 identifies theassociated scoring category, for example by displaying an identificationvideo simulated dice 905 displaying the number of the scoring category.Additionally, the second display area 903 is used to indicate a currenttarget number for a turn, preferably by changing color to indicate thatthe number of the associated scoring category is the active targetnumber. Also, the second display area 903 is preferably utilized tochoose a target number from amongst those displayed by an equal numberof the simulated dice 541 when necessary. The player chooses a targetnumber by touching the second display areas 903 associated with thechosen target number. The second display area 903 which the player maytouch to choose a target number blink or change color or size orotherwise provide visual indication of the choices available.Additionally, once a scoring category for a given number has beenfilled, the indicator for the associated second display area is replacedfor the remainder of the game by a non-numerical symbol 907, for examplethe letter “Z” or a graphic symbol of a piece of fruit, or as desired.

In alternative embodiments, display of accumulated points,identification of score category, indication of current target number,indication of available choices of target number, and indication offilled categories (and in other embodiments more or fewer functions asdesire) are divided between at least two display areas, in variouscombinations as desired.

Once the game has ended, the computer program 601 evaluates the player'sscore against other current scores to determine if a progressive jackpotwill be awarded on a daily, weekly, monthly, or yearly basis. If theplayer has a currently qualifying score, the computer-controlled slotmachine 101 prints 821 a voucher for the player with a control numberand other pertinent information for later redemption, if the score is awinner. In various embodiments, jackpots are awarded for achieving highscores, for achieving high scores low scores, or for achieving both highand low scores as desired.

Another embodiment of a game of the present invention will be describedwith reference primarily to FIGS. 10-11. This game is referred to hereinas the game of Z Hot Dice.

FIG. 10 illustrates a touch sensitive display 1015 for implementing thegame of Z Hot Dice. A scorecard 1001 area is provided in an upperleft-hand corner. The scorecard 1001 displays information regarding aparticular event, the pay table for that event, prior played events, andwin totals for each prior played event and the current event.

The scorecard 1001 includes six columns 1002, the number of columnsbeing the same as the number of sides of dice. During game play, asdescribed below, a target number is associated with one of the columns1002, the target numbers comprising one of the numbers associated with aside of a dice (i.e. the numbers one through six). At a top of eachcolumn 1002 is provided a target number indicator 1003. In oneembodiment, before a target number has been selected, this indicator1003 displays a “Z” or other symbol (or nothing). A central portion 1004of each column 1002 indicates the payout which will be awarded to aplayer for receiving a particular combination of the target number(s).

In the embodiment illustrated, the central portion 1004 is arranged todisplay payouts for receiving 3 of a Kind, 4 of a Kind, 5 of a Kind orSix of a Kind of the target number. A win total 1005 is provided at thebottom of each column 1002 for indicating the total payout or winningsto the player for a particular event. Those of skill in the art willappreciate that other winning combinations may be provided, such as afull house (i.e. three of the target number along with two of anothernumber).

The display 1015 displays a number of simulated dice 1041, in a similarmanner to that described above. Below each simulated dice area 1041 is ahold button 1043. Each button 1043 is associated with one of thesimulated dice 1041 and, as described in more detail below, arranged topermit a player to “hold” the a particular simulated dice 1041 in afixed position.

A number of other display areas are provided for displaying gameinformation. For example, a message area 1047 is provided for displayingthe amount of winnings in a jackpot pool. A grand total area 1039 isprovided for indicating to the player their total score for the wintotals 1005 of all columns 1002. In addition, a qualify score 1040 isdisplayed so that the player may determine if his or her grant total issufficiently high to qualify for a bonus or jackpot (as describedbelow).

A new game button 1051 is provided for permitting a player to begin anew game. As described in more detail below, once a player has placed awager, a text messages area 1045 displays winnings paid or otherinformation for a player. The player may bet or wager credits in singleincrements with a “Bet 1” button 1055, or may bet or wager a maximumallowed number of credits using a “Bet Max” button 1056. A credits area1046 displays the credits belonging to the player.

A spin button 1049 is provided for permitting a player to effectuate aspin of the simulated dice 1041. A pause game button 1059 is providedfor permitting a player to pause a game in progress. A player may electto cash out by pressing a collect button 1063.

As described in more detail below, while in one arrangement the userinterface or screen comprises a touch screen arranged to displayinformation to a player and receive input therefrom, the user interfacemay comprise a combination of electrical and mechanical devices. Forexample, one or more of the buttons may comprise electro-mechanicalbuttons which may be depressed by a player. Those of skill in the artwill appreciate that many players like the “tactile” feel of buttons ascompared to touch screen input. Further, while the display areas arediscussed separately, they may be integrated or be arranged in a numberof ways other than as shown.

A method of play of the game of Z Hot Dice will be described withreference to FIG. 11. In a first step 1120, a player inserts a number ofcoins or provides other consideration for playing the game. Theconsideration may be dollar bills, credits from a player card or thelike.

In a step 1122, the player presses the new game button 1051 to initiatea new game. In one or more embodiments, the gaming apparatus isconfigured such that if the player presses the new game at any timeduring the pendency of a game, the player is prompted to press the newgame button again if the player actually intends to start a new game.This serves to reduce the likelihood that the player may accidentally orunintentionally press the new game button 1051 and cause a new game tobegin. The prompt message may be illuminated in the text message box1045.

In a step 1124, the player places a wager or bet. In one embodiment,this step comprises the player pressing the “Bet 1” button 1055 or the“Bet Max” button 1056. In one embodiment, a player is permitted to betbetween one and five credits. Each credit may comprise any of a numberof values, such as $0.05 U.S., $0.10 U.S., $0.25 U.S. or the like. Theplayer may utilize the “Bet 1” button 1055 to place wagersincrementally, or press the “Bet Max” button 1056 to place a maximumbet. The payouts displayed on the central portions 1004 of the columns1002 may be updated, as necessary, to reflect an increased payout forachieving a predetermined winning combination when the player increasesthe amount wagered.

In a step 1126 the player presses the spin button 1049. Upon depressingthe spin button 1049, the simulated dice 1041 spin or move (such as in amotion simulating a “reel” displaying die faces), and then stop, asdescribed above to simulate the random roll of dice.

At this point, six simulated die 1041 are displayed to the player, eachdice 1041 displaying one face, and thus one number, towards the player.In the arrangement illustrated in FIG. 10, the simulated die 1041display a five, a one, a six, a two, another two, and another five.

In a step 1128, the player is then permitted to “hold” the dice whichthat player wishes to play. The held dice identify a selected targetnumber, the target number being that number shown on the face of theheld dice. For example, in the arrangement illustrated in FIG. 10, theplayer may elect to hold the simulated die 1041 displaying fives. Insuch event, the player presses the right-most and left-most buttons1043, and the target number then comprises five.

In a step 1130, when the player makes a selection, the target number isdisplayed in the first available column 1002 of the scorecard 1001. Inone embodiment, the first available column comprises the left-mostcolumn 1002 which has not been utilized during the game. Preferably, thetarget number is illustrated by replacing the “Z” or other symbol in theindicator 1003 with a dice displaying the target number. In the examplegiven above, a dice displaying a five would be displayed in theleft-most column 1002.

In one or more embodiments, a player is not permitted to select as atarget number a number which has already been played in a particulargame. If the player attempts to do so, a message may be displayed in thetext message box 1045 to the effect that the selected number has alreadybeen played and the player must either select a new target number orspin again. Another spin may be required where the first spin does notresult in the display of any available target numbers (as describedbelow, after a target number has been played, it is preferably removedfrom the simulated die 1041 and will not be re-displayed). In addition,if the player selects more than one number (such as a simulated dice1041 displaying a five and another displaying a two) the player beinstructed that the action is not permitted and the player must selectonly one target number.

Preferably, when a number is selected, the particular column 1002 ishighlighted, such as in brightness or a different color, to aid the userin identifying which information is pertinent to the present round ofthe game.

In one or more embodiments, the particular payout is dependent upon theplayer's wager, with the payout increasing with an increasing wager. Setforth below are possible paytables for wagers of one, two, three, fourand five coins or bet increments for each target number. As will beappreciated, the payout increases as the number of target numbers playedincreases (for reasons described below). Of course, a variety of payoutsmay be different than those illustrated.

If after the first spin and hold, the player has a winning combinationof simulated dice 1041, then the win total is indicated in the win totalarea 1005 of the scorecard 1001, and the text message box 1045 mayindicate the winnings. For example, in the event upon the first spin ofthe game the spin results in four simulated dice 1041 showing a five,then the player may hold these four simulated dice for a “4 of a Kind”of a target number of fives. The payout for this combination may then beindicated in the win total area for the first column 1002, and the textmessage box 1045 indicate the winnings to be paid.

In one embodiment, payouts for combinations of target numbers which areeliminated may be removed from the scorecard 1001. For example, in theabove-referenced example, the payout for a 3 of a Kind may be removedfrom the first column 1002, since the player has already received atleast a 4 of a Kind. In addition, the payout which the player hasalready received upon the first spin for that target number may behighlighted to bring to the attention of the player that he or she hasalready won. This highlighting may be by displaying the payout in adistinguishing color or brightness or other means available. The word“paid” may be indicated in the particular area of the scorecard 1001 aswell.

In accordance with the present invention, in a step 1132, after holdingone or more of the simulated dice 1041, or after an indication that nodice can be held, then the player presses the spin button 1049 again.All of the simulated dice 1041 which were not held spin and then stop,again displaying a number.

In a step 1134, the total number of simulated dice 1041 displaying thetarget number after the second spin are then counted for determiningwhether a payout is to be awarded. A win total is displayed in the wintotal area 1005 of the particular column. This win total may be 0, inthe event the player did not receive a sufficiently high number ofsimulated dice 1041 displaying the target number (for example, a playermay elect to hold two dice showing the target number after the firstspin and not receive any additional dice showing the target number afterthe second spin, thus not receiving a minimum three of the target numberfor an award). The payout for that “round” may then be updated in thetext message box 1045.

In a step 1136, the win totals from all win total areas 1005 are summedand displayed as a total score in the total score area 1039. Preferably,a qualifying score for a jackpot bonus is displayed in the qualifyingscore area 1040, again which the player may compare their score.

In a step 1138 it is determined if the player wishes to cash out. Thisis indicated by a player pressing the collect button 963. In such event,any accumulated winnings and credits are paid to the player. In thatevent, the game ends.

In a step 1140, it is determined if the player wishes to pause the game.If the player wishes to pause the game, the player pushes the pause gamebutton 1059. A process is then initiated by which the player may leavethe game and being play at a later time and even at different gamingmachine, as described in more detail below.

If the player wishes to continue the game, it is determined in a step1142 if all of the columns 1002 of the scorecard 1001 are filled. If so,then the player has completed the game. In a step 1146, the player'stotal score is compared to the qualifying score to determine if theplayer qualifies for participation in the jackpot. If the playerqualifies, then in a step 1148, the player is provided with a voucher orthe like, in similar manner to that described above with respect to thegame of Z Sixty Six.

In a step 1144, after a particular target number has been played in around, that target number is replaced on each simulated dice 1041 withanother symbol or is removed. As described above, this may be a symbol,such as a “Z,” or a picture of a fruit or the like. In one embodiment,it is preferred that the replacement symbols be different so that at notime can a player receive a sequence of the same symbols during a spin.Such may be confusing to a player and lead a player into believing thatthey have spun into a winning combination. For example, the replacementsymbols may comprise an X on the first simulated dice 1041, an O on thesecond simulated dice 1041, an X on the third simulated dice 1041 and soon, so that if a player spins and the simulated dice stop on thereplacement symbols, they display XOXOX. In a preferred embodiment, theside of the dice is effectively made blank or the symbol removed frompreventing its further display.

In another embodiment, the replacement symbols may actually be arrangedso that a player may spin into a new bonus combination for which apayout is awarded. For example, each number or dice face may be replacedwith a $ symbol, such that during later play if the player receives adisplay of all of these symbols after a spin, the player is awarded aspecial prize or payout.

If all of the columns 1002 of the scorecard 1001 are not filled, theplayer may, repeating again to step 1124, place a bet or wager. Theplayer may be provided with an indication in the text message box 945after a given round that they may place a bet to continue with the game.

The game then continues as described above. It will be appreciated thatafter a first target number has been played, a spin of the simulateddice 1041 may result in a display of all of the remaining numbers and/orthe symbols used to replace the already played target number. As thenumber of played numbers increases, the probability of receiving atarget number decreases. For this reason, as detailed above, the payoutfor receiving a winning combination of each target number increases asthe game progresses.

The player may continue playing until each of the target numbers onethrough six, have been played (in any order). At such time, the totalscore for the player is compared to the qualifying score to determine ifthe player is entitled to participate in a jackpot or additional play.Regardless of the outcome, the player must then begin a new game tocontinue play.

Another embodiment of a game of the present invention will be describedwith reference primarily to FIGS. 12-13. This game is referred to hereinas the game of Z Jackpot Dice.

The fourth reel ispreferably arranged to display the letter “U” in the colors of red,white and blue. The fifth reel is preferably arranged to display theletter “S” in the colors of red, white and blue.

It will be appreciated that the reels 1241 may comprise a displayedimage on a video display. In one or more other embodiments, the reels1241 may comprise mechanical reels having one or more of the imagesprinted thereon and/or capable of being displayed thereon. In general,each reel 1241 is arranged to simulate a throw or spin of an imaginarynine-side dice having sides displaying the above-described numbers andsymbols. Thus, as one aspect of the invention, dice or similar physicalitems are represented either graphically or on a physical reel.

Below each reel 1241 is a hold button 1243. Each button 1243 isassociated with one of the reels 1241 and, as described in more detailbelow, arranged to permit a player to “hold” the position of aparticular reel 1241 in a fixed position.

A number display areas are provided for displaying related gameinformation. For example, a message area 1247 is provided for displayingthe amount of winnings in a jackpot pool. A grand total area 1239 isprovided for indicating to the player the total score of the win totals1205 of all columns 1202. In addition, a qualify score 1240 is displayedso that the player may determined if his or her grant total issufficiently high to qualify for a bonus or jackpot (as describedbelow).

A new game button 1251 is provided for permitting a player to begin anew game. As described in more detail below, once a player has placed awager, a text messages area 1245 may be used to display information,such as game play information. The game play information may beaccessible by pressing an information button 1270.

Display areas are provided for displaying winner paid information 1271,bet information 1272, and credit information 1273. The player may bet orwager credits in single increments with a “Bet 1” button 1255, or maybet or wager a maximum allowed number of credits using a “Bet Max”button 1256.

A spin button 1249 is provided for permitting a player to effectuate aspin of the simulated dice 1241. A player may elect to cash out bypressing a cash out button 1263.

As illustrated, a coin acceptor 1213 and bill acceptor 1214 are providedfor accepting wagers by a player. A player card reader 1275 is providedfor reading a player card. The player card 1275 may contain creditswhich can be used to place bets, may contain player information forreading by the machine, and may store game information, such as aqualifying score, as described in more detail below. A ticket dispenser1276 is provided for dispensing tickets. As described in detail below,the ticket information may comprise game information, such anin-progress or completed game information.

A method of play of the game of Z Jackpot Dice will be described withreference to FIG. 13. In a first step 1320, a player inserts a number ofcoins (as by coin acceptor 1213), bills (as by bill acceptor 1214) orprovides other consideration for playing the game. Consideration mayalso comprise credits from a player card or the like.

In a step 1322, the player places a wager or bet. In one embodiment,this step comprises the player pressing the “Bet 1” button 1255 or the“Bet Max” button 1256. In one embodiment, a player is permitted to betbetween one and five credits. Each credit may comprise any of a numberof values, such as $0.05 U.S., $0.10 U.S., $0.25 U.S. or the like. Theplayer may utilize the “Bet 1” button 1255 to place wagersincrementally, or press the “Bet Max” button 1256 to place a maximumbet.

In a step 1324 the player presses the spin button 1249. Upon depressingthe spin button 1049, the reels 1241 spin or move (either by mechanicalrotation or by computer generated graphics) and then stop. At thispoint, one symbol is displayed in association with each reel 1241. Inthe arrangement illustrated in FIG. 12, the symbols six, white O, blueN, one and red S are displayed.

In a step 1326, it is determined if the player placed the maximum bet.If so, then in step 1328 it is determined if the player has received aspecific combination of displayed symbols on the reels 1241. In one ormore embodiments, a player is declared a winner if the player receivesthe symbols spelling BONUS. In one embodiment, if the player receivesthe symbols spelling BONUS in mixed colors, then the player is awardedthe bonus amount in the display 1206 for the present column. If theplayer receives the symbols spelling BONUS in the same colors (i.e. allred, white or blue) then the player is awarded the bonus amount in thedisplay 1206 for all columns 1202.

In one or more embodiments, a player is declared a winner if the playerreceives the same number on each of the reels 1241 (i.e. all ones,twos), and that number has not already been played. In a preferredembodiment, when the player receives the same number on each of thereels 1241, then the player is awarded the payout for 5 of a Kind aswell as the bonus amount.

If the player is a winner, then in step 1329, the total of any winningsis displayed in the total 1205 portion of the column being played. Inthe preferred embodiment, the column being played is the left-mostcolumn 1202 which has yet to be played. The totals of all column 1202totals are displayed in the total score area 1239.

As an example, if a player receives BONUS spelled in other than symbolsof a single color, then the player receives the bonus amount 1206 forthat column. That amount is then placed into the total portion 1205 ofthat column and then indicated in the total score area 1239 along withany other previous total amounts. If a player receives BONUS spelled ina single color, then the player receives the bonus amount 1206 for eachand every column. In such event, the totals 1205 for each column 1202are updated to reflect this winning, as is the player's total score. Ifa player receives a 5 of a Kind of a new target number, then the playeris awarded the payout for a 5 of a Kind and the bonus amount, and thefirst open column 1202 is highlighted and the target number displayedthereabove.

In a step 1330, once the player has been declared a winner, it isdetermined if the player received a win by a 5 of a Kind or receivingthe BONUS symbols. If the player received a 5 of a Kind win, then instep 1332, it is determined if the player wishes to cash out (as via astep 1348 as described below). If the player won by receiving the BONUSsymbols, then the player is entitled to respin again in an attempt toobtain a combination of target numbers, as in step 1224. Of course, ifthe player again receives a win on the first spin, the process repeats.If the player received the same number on each of the reels, i.e. a 5 ofa Kind, then the play for that particular target number is completed andthe player moves to the next round. In one or more embodiments, theplayer may be required to place another bet in order to spin again afterhaving received a win by hitting the BONUS win.

If in step 1326 it is determined that the player did not place a maximumbet, then in step 1334 it is determined if the player received a 5 of aKind of a new target number. If so, then in step 1336, the player isawarded the payout for that combination, and the award is displayed inthe appropriate column. It is next determined if the player wishes tocash out in step 1348.

If in steps 1326 and 1334 it is determined that the player did notreceive a BONUS win or a 5 of a Kind, then in step 1338, the player ispermitted to “hold” any of the reels 1241 which display a number. Whenthe player holds a particular number, that that number becomes thetarget number. For example, referring to FIG. 12, the player may wish tohold the six displayed in the first column 1202.

In a step 1240, when the player makes a hold selection, the targetnumber is displayed in the first available column 1202 of the scorecard1201. In one embodiment, the first available column comprises theleft-most column 1202 which has not been utilized during the game.Preferably, the target number is illustrated by illustrating the targetnumber on the dice at the top of the column. In the example given above,a dice displaying a six would be displayed in the left-most column 1002.

In one or more embodiments, a player is not permitted to select as atarget number a number which has already been played in a particulargame. If the player attempts to do so, a message may be displayed in thetext message box 1245 to the effect that the selected number has alreadybeen played and the player must either select a new target number orspin again. Another spin may be required where the first spin results inonly numbers which have already been utilized. In addition, if theplayer selects more than one number (such as a simulated dice 1241displaying a five and another displaying a two) the player be instructedthat the action is not permitted and the player must select only onetarget number. Also, a player is not permitted to hold any of thenon-numeric symbols, such as B, O, N, U or S.

Preferably, when a number is selected, the particular column 1202 ishighlighted, such as in brightness or a different color, to aid the userin identifying which information is pertinent to the present round ofthe game. In addition, once a particular target number is selected, thepayouts are highlighted in the central payout portion 1204 of thescorecard 1201.

In one or more embodiments, the particular payout is dependent upon theplayer's wager, with the payout increasing with an increasing wager.These payouts may be similar to those described and illustrated above.

In one embodiment, payouts for combinations of target numbers which areeliminated may be removed from the scorecard 1201. For example, thepayout for a 3 of a Kind may be removed from the column 1202 beingplayed when the player has already received at least a 4 of a Kind. Inaddition, the payout which the player has already received upon thefirst spin for that target number may be highlighted to bring to theattention of the player that he or she has already won. Thishighlighting may be by displaying the payout in a distinguishing coloror brightness or other means available. The word “paid” may be indicatedin the particular area of the scorecard 1201 as well.

In accordance with the present invention, in a step 1342, after holdingone or more of the reels 1041, or after an indication that no reels 1241can be held, then the player presses the spin button 1249 again. All ofthe reels 1241 which were not held spin and then stop, again displayinga number.

In a step 1344, it is determined if the player has received anypredetermined winning combinations. If the player did not hold any ofthe reels 1241, it is possible that on the second spin the playerreceived the symbols spelling BONUS. Preferably, the player is awarded awin as described above for spelling BONUS, if the player has placed themaximum bet. In any event, if the player spells BONUS, that player isentitled to an extra spin in order to permit the player to receive themaximum number of the target numbers.

It is also determined if the player has received a combination of thetarget number which qualifies as a win. In the embodiment illustrated,the player is a winner if he or she receives at least three of thetarget number, such as 3 of a Kind, 4 of a Kind or 5 of a Kind of thetarget number, or if the player receives a full house (i.e. 3 of a Kindof the target number plus a pair of another number).

A win total is displayed in the win total area 1205 of the particularcolumn. This win total may be 0, in the event the player did not receivea winning combination (for example, a player may elect to hold two diceshowing the target number after the first spin and not receive anyadditional dice showing the target number after the second spin, thusnot receiving a minimum three of the target number for an award). Thetotal payout to the player may be updated in the winner paid displayarea 1271.

In a step 1346, the win totals from all win total areas 1205 aredisplayed, then summed and displayed as a total score in the total scorearea 1239. Preferably, a qualifying score for a jackpot bonus isdisplayed in the qualifying score area 1240, again which the player maycompare their score.

In a step 1348 it is determined if the player wishes to cash out. Thisis indicated by a player pressing the collect button 1263. In suchevent, any accumulated winnings and credits are paid to the player. Inthat event, the game ends.

If the player wishes to continue the game, it is determined in a step1332 if all of the columns 1202 of the scorecard 1201 are filled (i.e.all of the target numbers have been played). If so, then the player hascompleted the game. In a step 1350, the player's total score is thencompared to the qualifying score to determine if the player qualifiesfor participation in the jackpot. If the player qualifies, then in astep 1248, the player is provided with a voucher or the like, in similarmanner to that described above. This voucher may be dispensed by thejackpot ticket dispenser 1276.

If all of the columns 1202 of the scorecard 1201 are not filled, theplayer may, repeating again to step 1224, place a bet or wager. Theplayer may be provided with an indication in the text message box 1245after a given round that they may place a bet to continue with the game.

In a preferred embodiment, after a particular target number has beenplayed in a round, that target number is removed from each reel 1241.Preferably, the space for the removed target number is made blank. Inother embodiments, as described above, the symbol may be replaced.

Further, upon the beginning of the next round, the column 1202 for thelast target number is darkened or the like so that the player'sattention is directed to the now active column 1202. It is preferred,however, that any winning amounts to the player still be displayed inthe prior columns 1202 for identification by the player. In addition, itis preferred that the bonus amount for each played column be removed soas to not confuse the player. In such event, the bonus amount for eachpreviously played column is placed in a bonus pool for award to theplayer in the event the player receives a combination of the lettersBONUS in all of the same color.

The game then continues as described above. It will be appreciated thatafter a first target number has been played, a spin of the reels 1241may result in a display of all of the remaining numbers and/or thesymbols used to replace the already played target number. As the numberof played numbers increases, the probability of receiving a targetnumber decreases. For this reason, as detailed above, the payout forreceiving a winning combination of each target number increases as thegame progresses.

It will be appreciated that the particular symbols which are utilized inthe game of Z Jackpot Dice may vary. For example, the non-numericsymbols need not comprise the letters B, O, N, U and S, and do not needto comprise one of each in three different colors. For example, thenon-numeric symbols might comprise pictures of fruit or other items.Differing combinations of the non-numeric symbols may be achievedthrough color, size or other designation. In addition, a greater orlesser number of non-numeric symbols may be provided with each reel. Forexample, there may be only two, or as many as four or more of each ofthe letters, each in different colors.

It will also be appreciated that in one or more embodiments, player maybe permitted to hold one of the non-numeric symbols, i.e. B, O, N, U,and/or S, in an attempt to gain a winning combination of such symbols ona second spin or play.

While a specific order of events has been described for the play of ZJackpot Dice, the order of events and activities may be varied from thatabove. For example, the times at which columns are highlighted, playednumbers are indicated at the top of the columns and the like may varyfrom that described above. In this regard, the above-description issimply exemplary of an implementation of the concepts of the Z JackpotDice game.

Utilizing a local area computer network 301 and a wide area computernetwork 401, multiple players may play the game Z Sixty Six, Z Hot Diceor Z Jackpot Dice against one another instead of “against the house.”Utilizing a local area computer network 301, each participating playerdeposits money into an individual computer-controlled slot machine 101for each spin. The player who achieves the highest game score of all ofthe players who are participating in that multiple player game on thelocal area computer network 301 wins the money deposited by the variousparticipating players (typically, minus a percentage for the house). Thesame methodology can be utilized across a wide area computer network401, allowing players at different physical locations to compete againsteach other in real time.

As described above, in any of the games of the invention, includingCheck, Z Sixty Six, Z Hot Dice and Z Jackpot Dice, a player may attemptto obtain a high total score for qualifying for a jackpot. In one ormore embodiments, the jackpot comprises a percentage of the monieswagered by the players of the game(s). In this manner, the jackpotcontinues to increase over time with play, and over time, may comprisemulti-million dollars in size. The jackpot may comprise monies belongingto the establishment offering the game, and may comprise other than cashprizes.

In one or more embodiments, jackpot prizes are awarded at variousintervals. The interval may be daily, weekly, monthly, yearly, or thelike. The intervals may vary or be evenly spaced.

In a preferred embodiment, jackpot prizes are awarded to one or moreplayers who have achieved a high score playing the game. In oneembodiment, a set number of players, such as twenty, who have achievedthe highest scores playing the game during a jackpot interval mayparticipate in the jackpot. For example, the jackpot may be awarded onthe 1^(st) of each month, with the players who have achieved the twentyhighest scores during the previous month participating in the jackpot.Of course, a gaming establishment may determine the total number ofparticipants.

The participation by the players in the jackpot may be even (i.e. dividethe jackpot by the number of participating players) or may be on asliding or other scale where the higher the player's ranking, thegreater that player's participation in the jackpot. The jackpot may alsobe a fixed amount for each player, or be fixed based on their ranking.

Of course, the manner by which a player is determined to be entitled toparticipate in the jackpot may vary. For example, players having thelowest scores may be entitled to participate.

Those of skill in the art will appreciate the enticement of such ajackpot award system to a player. In this arrangement, a player need notreceive any specific predetermined winning combination or point total.Instead, a player need only achieve a sufficiently high score to beincluded in the jackpot award. The high score is not fixed, but isdependent upon the scores of other players. Thus, during any particularjackpot interval, the score which a player needs to achieve toparticipate in the jackpot may vary.

A player may track whether or not they are in the running to win thejackpot during a given payout interval. The player may compare theirscore(s) against the minimum qualifying score at any time to determineif they are still entitled to participate in the jackpot. A player maydetermine that their score is no longer high enough to qualify forjackpot participation (such as by reason of a number of later playersreceiving higher scores and displacing the player from the top twentyhighest scores). In such event, a player may play one or more gamesbefore the award of the next jackpot in an attempt to re-qualify.

In one or more embodiments, the jackpot qualifying scores may bepublished, such as on the Internet, permitting a player to convenientlytrack their participation. In addition, the list of winners of aparticular jackpot may be published. The winners may be listed bywinning number, which number is printed on the player's voucher. Theplayer may then redeem the voucher for their jackpot award at a gamingestablishment or other location.

Alternatively, achieving a predetermined score may be utilized forawarding a predetermined jackpot. For instance, if a player achieves aperfect score, meaning the theoretically highest score for eachcategory, then a jackpot may be awarded for such achievement.

In one or more embodiments of the invention, a number of differentjackpot prizes may be provided, the prizes associated with differentintervals. For example, a first jackpot prize may be associated with aweekly interval, and another jackpot prize associated with a monthlyinterval. In one embodiment, jackpot prizes associated with longerintervals may be larger than those which are associated with shorterintervals.

In this embodiment, a player may be permitted to select which jackpotprize they wish to play for. For example, a player may begin a game andbe permitted to select the desired jackpot to play for. A player mayselect the “weekly” jackpot. The player's game result is then used indetermining whether the player is entitled to the weekly jackpot at thetime the jackpot is awarded. In such an embodiment, the player's gameresult or score is not associated with participation in other jackpots,such as the monthly jackpot.

In another embodiment, a player may be permitted to attempt to win morethan one jackpot. For example, for an additional bet, a player may bepermitted to participate in one additional jackpot. For yet anotheradditional bet, a player may be permitted to participate in anotheradditional jackpot. By way of example, upon a player placing twoadditional bets, a player may attempt to win both the weekly and monthlyjackpot using the score or result of their game.

In another embodiment, a jackpot or prize may be awarded for gameoutcomes (such as highest score) of a group or number of games. Forexample, a jackpot or prize may be awarded to the player receiving thehighest score while playing a game of a group or set of 100 gamesplayed. In one embodiment, each gaming machine may be arranged toprovide such a jackpot or prize for each set or group of games played.

It will be appreciated that the predetermined winning combinations andtheir payouts may vary from those described and illustrated herein. Forexample, instead of attempting to achieve a five of a kind of a givennumber, a player may be directed to achieve a full house, a straight orother combinations. In one or more embodiments, especially when bonusesor jackpots are not awarded, winning combinations may include the morecommonly obtained 2 pair or even a single pair. It will be appreciatedthat when a portion of the wager is diverted to the generation of bonusand jackpot payouts, paying on such commonly occurring combinations isless desirable, as the hold for the game may be minimal or non-existentto the house.

In one or more embodiments of a game in accordance with the invention,bonus points or awards may be provided when a player receives particularindicia combinations. In one embodiment, a player may be awarded abonus, such as bonus points, for completing a particular scoringcategory on a first spin or roll of the dice. For example, in the eventthe player receives five “4's” on first roll of the dice, thus fillingthe category for “4's” then the player may be awarded bonus points inaddition to the points awarded for the total of “4's.” Referring to FIG.5(a), the player may be awarded 20 points for the five “4's” plus abonus of 300 points for completing the “4's” category on the first spin.

In one embodiment, a bonus or bonus points may be awarded for receivinga combination or completing a category on other than the first spin orroll. For example, a first bonus may be awarded for receiving acombination or completing a category on the first roll, a second bonusfor doing so on the second roll, and a third bonus for doing so on thethird roll. If upon the third roll the player did not complete thecategory, then no bonus may be awarded. For example, if after the thirdroll the player received only three “4's,” the player may be awardedonly the 12 points for the “4's.” In one embodiment, the bonusassociated with receiving a combination or completing a category maydecrease for each additional spin necessary.

In addition, the total number of reels or simulated dice may be varied.In the examples illustrated, 5 or 6 of such simulated dice or reels areillustrated and described. However, the games may be played with alesser number or greater number (i.e. such combination as 7 of a Kindbeing obtainable, or a maximum of 4 of a Kind). Those of skill in theart will appreciate that as the total number of available combinationschanges, the payouts may need to be changed in order to both entice aplayer into playing and yet prevent the house from risking loss.

In the above-described games, a player may preferably save a game inprogress by pressing the touch-sensitive save-restore game button559/pause game button 1059. The computer program 601 then utilizes themachine-readable medium reading and writing device 129 to write thepresent scores and game states to a card, voucher (such as a printedticket or token) or other medium which the player can take with them.The player may later resume the saved game by inserting such card orvoucher of machine-readable medium into the reading and writing device129 of any computer-controlled slot machine 101. The saved gameinformation is then read from the card or voucher to initialize theconditions and states of the computer-controlled slot machine 101. Invarious embodiments, a magnetic or optical or semiconductor medium maybe used as desired to store and transfer scores and game states andother pertinent data on such card or voucher produced by the video slotmachine 101. In one or more embodiments, when the player elects to pauseor save a game in progress, game state information is generated. Thisinformation may be stored to the medium which is provided to the player,or may be stored remotely, such as at a central server associated withthe games when they are linked. In such event, a code or otherinformation need only be stored or associated with the medium providedto the player. When the code is read or inputted into a game at a latertime, the code may cause the game to access the game state informationstored separately from the medium. In this manner, a player may bepermitted to cease playing a game at a first time and pickup that samegame at a later time, and even at a different gaming station offeringthe game. It will be appreciated that such a similar function may beapplied to the game of Z Jackpot Dice or even games other than thosedescribed herein, such as those games now known or later invented.Further, it should be noted that the games may be arranged so that aplayer may engage the pause function, as well as the cash-out and otherfeatures of the games, at times other than those specifically describedabove. For example, a player may be permitted to pause a game at anypoint, and not specifically only after the completion of a given roundof play.

Another embodiment of a game of the present invention will be describedwith reference primarily to FIGS. 14-16. This game is referred to hereinas the game of Draw Dice.

FIG. 14 illustrates a touch sensitive display 1415 for implementing thegame of Draw Dice. A payout table 1401 is provided in an upper left-handcorner. The payout table 1401 displays information regarding aparticular winning combination and the payout for the combination.

The payout table 1401 includes six columns 1402. In a first column arelisted a variety of particular combinations of indicia which may beobtained by play of the game described in more detail below. At a top ofthe remaining columns 1402 is a bet indicator 1403. Below each betindicator 1403 is a payout amount which indicates the payout which willbe awarded to a player for receiving a particular winning combination.

In the embodiment illustrated, the payout table 1401 displays payoutsfor receiving two pairs of 4's, 5's or 6's, 2 pair, 3 of a Kind, aStraight, a Flush, a Full House, a 4 of a Kind, a 5 of a Kind, a RoyalFlush or a Perfect Royal. The significance of these combinations will bedescribed below. Those of skill in the art will appreciate that otherwinning combinations may be provided, dependent upon the type of gamewhich is implemented.

The display 1415 displays a plurality of indicia. In a preferredembodiment, the indicia include a number of simulated dice 1441 (or atleast one face or side of a dice), in a similar manner to that describedabove. Below each simulated dice area 1441 is a hold button 1443. Eachbutton 1443 is associated with one of the simulated dice 1441 and, asdescribed in more detail below, arranged to permit a player to “hold”the a particular simulated dice 1441 in a fixed position.

A number of other display areas are provided for displaying gameinformation. For example, a jackpot bonus value 1039 is displayed

In order to play the game, the player is preferably required to place awager, such as by providing coins, dollar bills or other credit. Theplayer may bet or wager credits in single increments with a “Bet 1”button 1455, or may bet or wager a maximum allowed number of creditsusing a “Bet Max” button 1456. A credits area 1446 displays the creditsbelonging to the player. A coins bet area 1447 is provided fordisplaying the number of coins bet by a player on a given game.

A wide variety of other features may be provided. For example, a betcancel button 1448 may be provided to permit a player to cancel theirbet. Winnings may be displayed in a winner paid area 1449. A spin button1451 is provided for permitting a player to effectuate a spin of thesimulated dice 1441.

As described in more detail below, while in one arrangement the userinterface or screen comprises a touch screen arranged to displayinformation to a player and receive input therefrom, the user interfacemay comprise a combination of electrical and mechanical devices. Forexample, one or more of the buttons may comprise electro-mechanicalbuttons which may be depressed by a player. Those of skill in the artwill appreciate that many players like the “tactile” feel of buttons ascompared to touch screen input. Further, while the display areas arediscussed separately, they may be integrated or be arranged in a numberof ways other than as shown.

As described herein, a wide variety of combinations of indicia may beused to comprise the simulated dice 1441 or other indicia used in thegame. In the preferred embodiment of Draw Dice, there are five reels1442 or simulated reels. Each reel 1442 is capable of displaying symbolsor indicia comprising or representing each of the six sides of a dice1441. In a more preferred embodiment, each reel 1442 is capable ofdisplaying each of the six sides of a dice in each of a plurality ofcolors or otherwise including distinguishing attributes orcharacteristics. In one embodiment, each reel 1442 is capable ofdisplaying each of the six sides of a dice in each of three colors, suchas red, white and blue.

In one embodiment, play of the game results in each reel 1442 displayingone indicia as part of a resulting combination of a spin or event. Inone embodiment, a spin may result in a reel 1442 displaying a blank ornon-dice indicia which comprises part of the results of a spin. The reel1442 may also display indicia representing a side of a dice. Asillustrated in FIG. 16, while at most only one side of a dice or otherindicia (such as a blank space) comprises the result of a spin forpurposes of determining if a winning combination has been received,other indicia may be displayed and be viewed by a player.

In the preferred embodiment, the ability of the reels 1442 to displayeach dice side in three different colors or with other distinguishingattributes creates the opportunity for unique winning combinations, asdetailed in part above with respect to the payout table 1401. In oneembodiment, a winning combination may comprise a pair of 5's, whether ofthe same or different colors. The opportunity for a flush exists, theflush comprising a combination of dice of the same color, regardless ofvalue (i.e. regardless of which sides of the dice are shown). A royalflush comprises any combination of five simulated dice 1441 comprisingeach of the values 1-5 or 2-6, in any color. For example, a royal flushmay comprise the dice combination 5 blue, 3 red, 1 white, 2 blue and 4red. A perfect royal comprises any in sequence combination of simulateddice 1441 all of the same color. This requires that the simulated dicebe displayed in forward or reverse order 1-2-3-4-5, 5-4-3-2-1, 2-3-4-5-6or 6-5-4-3-2. Because each reel 1442 is capable of displaying the sidesof the dice in three colors, there are 3×4, or 12, ways to achieve theperfect royal flush. In addition, as a result of the fact that fivesimulated dice may be displayed in combination, the opportunity exitsfor a 5 of a Kind comprising five simulated dice showing the same sideor value. It will now be appreciated that by providing indiciacomprising the sides of dice, and multiples of each side of dice havingdistinguishing attributes, and by providing several reels, a widevariety of unique combinations of indicia are provided which maycomprise winning combinations. Further, because of the number ofvariable parameters, the payouts for winning combinations may beparticularly selected. For example, a gaming manufacturer orestablishment may wish to provide a particular percentage return onwagers placed, and may wish to pay winnings for combinations which arefrequently received. In both cases, such can be achieved using the manyvariable parameters associated with the indicia and reels.

It will be appreciated that the number of duplicates of each side of adice may vary, such as by having each reel 1442 capable of displayingtwo or four or more of each side of a dice. In such event, two colors orfour or more colors may be used to distinguish the duplicates of thesides of the dice. As stated above, other distinguishing attributes maybe provided, such as card suits, secondary values and the like. In oneembodiment, there may be multiples of each side of a dice each havingthe same attribute. For example, each reel 1442 may select an indiciafor display from a group which includes multiples of the same side of adice in the same color. It will be appreciated that such combinationsare useful in changing the odds of receiving a particular combination.As used herein, the term “selection” for purposes of determining whichindicia is to be displayed is not limited to the stoppage of a reel 1442having the indicia displayed, but may be simply as a result of acomputer generation or selection (such as randomly or randomly with oddsfactors) of the indicia, and then the display of that indicia or thestoppage of the reel at a point displaying that indicia.

In one embodiment, upon a second spin or display of indicia, each reel1442 is capable of redisplaying the same indicia (e.g. the group ofindicia from which the indicia is selected upon the second spin is thesame as upon the first spin). In another embodiment, once an indicia hasbeen displayed by a reel 1442, upon a second spin it can not bere-displayed.

In one or more embodiments, the reels 1442 may be capable of displayinga wide variety of indicia other than the dice indicia 1441. As statedabove, these indicia may comprise blank spaces or other non-diceindicia. In such event, the winning combinations may be varied. Forexample, the reels 1442 may be capable of displaying a colored spot,wherein that colored spot may be used to form a flush, but not astraight (since it has no associated value).

The present invention is not limited to the display of the dice sideindicia by video means. The indicia may be displayed in a variety ofmanners, such as on a mechanical reel, by hologram or the like.

A method of play of the game of Draw Dice will be described withreference to FIG. 15. In a first step 1520, a player inserts a number ofcoins or provides other consideration for playing the game, such asdollar bills. Consideration may also comprise credits from a player cardor the like.

In a step 1522, the player places a wager or bet. In one embodiment,this step comprises the player pressing the “Bet 1” button 1455 or the“Bet Max” button 1456. In one embodiment, a player is permitted to betbetween one and five credits. Each credit may comprise any of a numberof values, such as $0.05 U.S., $0.10 U.S., $0.25 U.S. or the like. Theplayer may utilize the “Bet 1” button 1455 to place wagersincrementally, or press the “Bet Max” button 1456 to place a maximumbet.

In a step 1524 the player presses the spin button 1449. Upon depressingthe spin button 1549, the reels 1442 spin or move (either by mechanicalrotation or by computer generated graphics) and then stop. At thispoint, one symbol is displayed in association with each reel 1441. Asdescribed above, the symbol may comprise a “blank.”

In a step 1526, the player elects to hold one or more of the reels 1442and associated displayed dice or other indicia. In one embodiment, theplayer may elect to hold none, one or more or all of the reels 1442.

In a step 1528, the player spins the non-held reels 1442 a second time.This step may be initiated by the player depressing the spin button1451. In this embodiment, each of the non-held reels 1442 is spun. Inthe event all of the reels 1442 have been held, then none of the reelsspin.

In a step 1530, the outcome of the game after the second spin isanalyzed in order to determine if a winning combination was received. Ifa winning combination was received, then winnings are awarded to theplayer in accordance with the payout table 1401, as per step S1532. If awinning combination was not received, then the game ends.

As illustrated, in the event the player placed the maximum bet andreceived a Perfect Royal combination, then the player is awarded a bonusamount. In a preferred embodiment, each time a player places a bet, theentire value of the bet is credited to the bonus or jackpot amount whichmay be won. In one embodiment, the bonus amount is initially creditedwith a base amount greater than the payout for the highest hand (i.e.Perfect Royal in this case) with the next smaller bet (i.e. 4 coins inthis case). Thereafter, all additional bet monies are credited to thebase amount, generating a total bonus or jackpot amount. In the eventthe player receives this predetermined winning hand with the maximumbet, the player is awarded the total bonus amount. It will beappreciated that this concept of generating a bonus or jackpot amountwhich increments by the fully value of the bet or wager may be appliedto a wide variety of games.

In one embodiment of the invention, when a player holds a particularreel 1442, the display of that reel or indicia changes so that only theheld indicia is displayed. This effect is illustrated in FIG. 16, wherethe player has elected to hold the fifth reel. As illustrated, when thisoccurs, the display of the reel 1442 changes so that only the held valueis displayed. This visually indicates to the player that the reel 1442has been held, and makes it easier for the player to see the resultingcombination of indicia for determining whether a winning combination hasbeen received.

In one embodiment of the invention, a multiplier (not illustrated) maybe displayed. The multiplier may cause one or more amounts won by aplayer to be increased. For example, a multiplier value may be indicatedon the display 1415. The value may comprise 2, 3, 4 or other values,including greater values, lesser values, and even 0. In the event aplayer obtains a particular predetermined combination, the value fromthe payout table 1401 for that win may be multiplied or increased by themultiplier value and then the new winning amount paid to the player. Itwill be appreciated that the multiplier value may be a value which isactually multiplied against the winning, or may comprise a value whichis added to the base winning. In one embodiment, the multiplier valuemay be randomly selected from a plurality of value and then displayed,or may increase with time, or be selected in accordance with a varietyof other criteria.

It will be appreciated that one or more aspects of the game of Draw Dicemay be applied to the other embodiments of the game described herein. Inaddition, one or more of the embodiments of the other games of theinvention may be applied to the game of Draw Dice.

It will be appreciated that games in accordance with the invention neednot be the same as those described above. In one or more embodiments,the game includes the step of removing from the set of symbols at leastone of the symbols, thereby reducing the possible number of combinationsachievable thereafter by the player. Preferably, as the number ofcombinations which the player may achieve are reduced, the payout forachieving a winning combination increases. In the embodiments describedabove, the symbols or indicia are or include the sides or faces of dice.As target numbers are played, those number or indicia are removed fromplay. Of course, such a game may utilize other indicia. For example,such aspects of the game may be applied to a “slot-type” machine whichincludes reels displaying symbols such as cherries, 7s, bells and thelike. As rounds, hands or the like of play are completed, the symbolsmay be removed randomly or in accordance with winnings combinationsreceived by the player.

In one or more embodiments, features such as jackpots and bonuses may beomitted. On the other hand, any combination of jackpots or bonuses asdescribed herein may be applied to such a game or any of the gamesherein.

In particular, a number of other alternate embodiments or alternatearrangements to the games other than as described above arecontemplated, and it will be appreciated that one or more of thefeatures described herein, whether or not described with a particulargame, may be applied to another. By way of example, a player may bepermitted to “hold” the simulated dice in the game of Z Sixty Six aswell as in the games of Check and Z Hot Dice. In addition, thereplacement symbols utilized in the games of Check and Z Sixty Six may,as in the case of Z Hot Dice, comprise symbols which either prevent aplayer from obtaining what appears to be a unique or winning combinationof replacement symbols, or may comprise a combination of symbols whichpermits a player to receive a winning combination of replacementsymbols.

In any of the embodiments, the replacement symbols may comprise nosymbol at all, but comprise a blank or an indicia which otherwise willnot contribute to a predetermined winning combination. A variety ofcriteria may be applied to the games of the invention for determiningwhen a player has qualified or completed a round or category. Forexample, as described above, a player may be required to receive atleast 3 of a Kind to start play. In one or more embodiments, a playermay be required to play until they achieve at least a 3 of a Kind beforeany score is attributed to a particular category (i.e. not just thefirst). For example, after completing a first target number if on thenext two spins the player achieves at most a pair, the player may berequired to place an additional wager and utilize two more spins in anattempt to gain at least 3 of a Kind. In other embodiments, such asdescribed above, the player may receive a zero score if they do notreceive a winning combination on each set of spins. For example, aftercompleting a first target number or category, if on the next two spins aplayer receives only a pair of the same indicia, the score for thatcategory may be credited as zero, and then the player forced to move tothe next target number or category.

In one or more embodiments of the invention, a player may be declared awinner for receiving other combinations of symbols/events. For example,a player may be paid a special award or winning or receiving at least 4of a Kind of each target number. For example, in the embodimentillustrated in FIG. 12, an additional column 1202 may be provided whichindicates the amount of a bonus the player may receive for obtaining a 3of a Kind, 4 of a Kind or the like of each of the target numbers in theother columns. Such a bonus may be utilized in addition to a“per-column” bonus as described above in the game of Z Jackpot Dice orthe jackpot as described herein.

In one or more embodiments of the invention, may as described above withrespect to the game of Check, not include the step of removing one ormore of the symbols as game progresses. Instead, the player may continueplay, attempting to achieve winning combinations, jackpots, bonuses (orother of the features/elements) using the same set of symbols as playprogresses.

In an alternative embodiment, the games of Check, Z Sixty Six, Z HotDice, Z Jackpot Dice or Draw Dice or other game variations describedherein may be played over the Internet or other wired/wirelesscommunications network/system among a random collection of players atdiverse locations, forming a virtual wide area network of such competingplayers.

In alternative embodiments, numerous other wagering games, including butnot limited to Poker Dice, and Aces in the Pot may be configured forplay and display on the display 115, and played over a local areacomputer network 401 or wide area computer network 501 ofcomputer-controlled slot machines 101.

In accordance with one or more embodiments of the invention, there is amethod of playing a game and a system for presenting a game includingmultiple players. Several arrangements of machines 101 in a networkconfiguration for use in presenting such a multi-player game areillustrated in FIGS. 3 and 4.

In a preferred embodiment of the invention, the process of game play ofgames played by more than one player is linked or commonly controlled.In one embodiment, a common controller controls the or governs the playof the multiple games. As one example, the common controller maycomprise a server 303 such as illustrated in FIG. 3.

In one embodiment, the controller provides control information to two ormore computer-controlled gaming machines (such as machines 101 in FIG.3). The control information may comprise a control signal transmittedover a network (or other communication link) connecting the controllerand the gaming machines, such as dedicated lines 311 as illustrated inFIG. 3.

In one or more embodiments, based on the control information, at leastone or more events associated with or regarding the play of the games bythe one or more players is dictated. In one embodiment, the one or moreevents comprise a game start, game stop or individual game play steps.In one or more embodiments, the aspect of these one or more events whichis dictated comprises the timing of the event. The dictated timing maycomprise a precise time or a time window or window by which an eventmust occur, as detailed below.

A preferred embodiment of the invention as applied to the game of Z HotDice will be described with reference to FIG. 11. In one embodiment,each of the players who wish to participate in the game provide credits.Preferably, the common controller generates a signal which defines thestart of the game, as in step 1122. In one embodiment, the controllersends a signal representing information to each gaming machine regardinghow soon the game will begin. This information may comprise a visibletimer, time clock, graph or other indicator which is displayed to theplayer of each gaming machine regarding the time at which the game willbegin. For example, the controller may send information which iscontinuously updated regarding the time until the game is to begin. Inone or more embodiments, each player wishing to participate in the gamemust have their credits provided before the game starts.

In one embodiment, at the start of the game the controller sends asignal to each gaming device polling that device for informationregarding credits placed. If the gaming device sends back a signalindicating that credits have been placed, then the controller may send asignal to the gaming device permitting further input to the player andindicating to the player that they are permitted to play the game. Ifthe gaming device sends back a signal indicating that credits have notbeen placed, then the controller may send a signal to the gaming devicepreventing the gaming device from accepting input from a player untilthe completion of the pending game. The signal may also cause the gamingdevice to present information to the player that the gaming device ispresently not usable.

Once the game starts, the controller sends a control signal to eachgaming machine instructing the player to place their bet, as in step1124. In one or more embodiments, the controller is arranged to generateand send information regarding a period of time during which the playeris permitted to take action. For example, the controller may send clockor timer data, as described below, which indicates to a player how long,or how much longer, they have to take the appropriate action.

Once the time period has ended, only players who placed bets are allowedto continue. Next, the controller is either arranged to cause the diceto spin (as in step 1126) or allow the player to effectuate the spin.The controller next sends a signal regarding a time during which eachplayer must make their section of held dice and the indicated target, asin steps 1128 and 1130. When this time period expires, the controllereither causes the respin or provides a period of time during which eachplayer may respin.

The win totals are then posted and the controller may dictate a periodof time during which a player may leave the game or continue with thegame by placing an additional bet (as in steps 1140, 1142 and 1144.

In one or more embodiments of the invention, the multiple players playagainst one another in an attempt to win a prize. In such an embodiment,the outcome of each player's game may be compared to the outcome of allother players' games for determining the winner of the multi-playerevent. For example, in the example of Z Hot Dice, each player mayattempt to obtain the highest total score (see element 1039 in FIG. 10).The player who receives the highest total score for a particular gamemay be awarded a jackpot. Other criteria may be utilized for determiningone or more winners of the multi-player game, such as lowest score orthe highest three scores. In a preferred embodiment, a player is awardedwinnings based on the outcome of their game, regardless of whether theirresult qualified them for winnings when compared to all other players.

In one embodiment other prizes may be awarded based on other criteria.For example, the player(s) who receives the highest score during aparticular round (i.e. a pair of spins in an attempt to fill a singlecategory) may be awarded a prize, such as money or bonus points towardstheir total score.

As one aspect of the invention, the order or sequence of the play of thegame by a plurality of players is generally synchronized or otherwisecontrolled. In the embodiment just described, the timing of each step ofthe game as played by the players is controlled from a time perspective.It will be appreciated that only the play of the game broadly need becontrolled from a time perspective. For example, the controller maydefine a window during which all players are entitled to a play anentire instance of the game.

As indicated, in one or more embodiments, the controller controls thetime or time periods for certain activities to occur, such as a playerinput. One or more embodiments of the invention include a method andsystem for providing time information to a player. In an embodimentwhere a player is permitted a time period during which an activity mustoccur in order for the player to proceed or for the player'sact/selection to occur, time period information may be displayed. Thetime period information may comprise numeric time information, graphicalinformation or other forms of information recognizable by a player. Forexample, the information may comprise a pie-type graph with remainingtime indicated as one portion of the graph illustrated in one color andexpired time indicated as a portion of the graph in another color.

In one or more embodiments, audible or visible alarms or alerts may beprovided to a player. For example, an area of the display may flash andindicate to a player that the player only has a short period of timeremaining (such as 1 minute, 15 seconds or the like) to take action.

In one or more embodiments, when the player takes action, the timeindicator may be removed or other information displayed to the playerindicating that the player's action/selection has been accepted. In oneor more embodiments, certain actions by a player may be rescinded and anew action/selection permitted. For example, a player may elect torescind particular held dice and hold different dice, so long as suchaction occurs during the particular time period or by the timeindicated.

In one or more embodiments, a method of game play is disclosed in whichone or more aspects of game play must occur within a particular timeperiod or before a certain time. If one or more of the acts or inputsare not provided within the required time, the player may be preventedfrom continuing further and completing the game.

Selections by a player, game state information and similar informationis preferably forwarded from each gaming device or machine to thecontroller. In the event a player does not take the necessary actionwithin the required time, then the controller may be adapted to send asignal to the gaming machine to cause the gaming machine to not acceptinput from the player for proceeding in game play. This same signal maycause the display of information to the player that the player did notact in sufficient time and that the player is not permitted to continueplaying.

In one or more embodiments, a player's bet may be refunded if the playerdoes not take action within the required time. For example, if a playerplaces a bet but does not then spin the reels within the required time,the player's bet may be credited back or refunded. Preferably, theplayer's bet is not refunded if the player fails to provide input afterone or more of the steps which define the outcome of the game occurs.For example, a player may not be entitled to a refund of their bet ifafter a spin of the dice the player does not hold one or more dice, assuch may allow the player to take advantage of the casino/house byceasing to act except where a favorable combination of dice are receivedon the first spin.

In one or more embodiments of the invention, the multiple gamingmachines which are used to present the games to the multiple players maybe located adjacent to one another or located remote from one another.For example, a plurality of gaming machines associated with a controllermay be located in a particular room or rooms of a casino. On the otherhand, the gaming machines may be associated with a local or wide areanetwork allowing the gaming machines to be located remote from oneanother and/or the controller. For example, one or more of the gamingmachines may be located in a first casino and other of the gamingmachines located in an entirely different casino.

In one or more embodiments, the controller need not be entirelycomputer. As one aspect of the invention, a human “caller” may beinvolved in the control of the multi-player game. The caller may provideinformation to players, such as instructions to take particular actions(e.g. “place bets,” “spin,” “hold dice”). The caller may also providetime information and generate or cause the generation of a controlsignal event. For example, the caller may cause the initiation of a timeperiod via a computer or other device associated with the controller orproviding input directly to the controller. The caller may provide aninput to the controller causing the controller to start a period of timerunning or set a time by which an event is to occur. In thisarrangement, the caller may provide gaps of time between events. Forexample, the caller may announce a two minute period of time duringwhich players are to engage in their first spin. The caller may thenallow a minute or two to lapse before starting a two minute time periodduring which the players are required to make dice hold selections.

As one aspect of the invention, the caller may be provided withinformation regarding player activities, such as the total number ofplayers and the number of players having made and/or not made aselection or engaged in the require activity. This information may beused by the caller to prompt players to take action or permit anextension of the time period for taking action.

A caller may be utilized even when the gaming machines are locatedremotely from one another. In one embodiment, the image of the callermay be transmitted to each player, such as by a separate communicationchannel and one or more displays which are visible to players of thegaming machines, or even by picture-in-picture display of theinformation to the player directly at the gaming machine. In one or moreother embodiments, a caller may be utilized even though the caller isnot present or visible to the player. For example, a caller may be usedto controller the game play, such as starting and stopping time periods,which time periods are only indicated to a player.

The arrangement of the system including the one or more devices forimplementing a method of multi-player game play in accordance with theinvention may vary. As indicated, in one embodiment, a plurality ofgaming machines or devices are associated with at least one controllervia one or more communication pathways. In one embodiment, each gamingdevice may be provided with its own gaming controller, such as includinga random number generator for generating game outcomes. The maincontroller may provide control information to each gaming machine, andeach gaming machine may be arranged to generate (within the control ofthe main controller) the game information specific to that gamingmachine, such as the outcome of a particular spin.

In another embodiment, all or substantially all of the game playinformation may be generated remotely from the gaming machine. Forexample, the controller including a random number generator forgenerating a plurality of game outcomes for the differing gamingmachines. This game play information may then be transmitted to eachparticular gaming machine.

The game which is played by multiple players may comprise a wide varietyof games other than the game of Z Hot Dice as described above. Forexample, any of the games herein may be implemented for multi-playerplay. Other games which are presently known may also be configured forplay in accordance with the method of the invention, such as the game ofvideo poker.

In one or more embodiments of the invention, information regarding eachplayer's own game play, including prior game play, and others' game playmay be presented. In one embodiment, information regarding a player'sprevious game play, such as previous resulting dice combinations andawarded points may be displayed. Such information may be useful to theplayer in assessing how to proceed with a present game or round of agame. In one embodiment, information regarding other players' gameresults may be displayed to a player. For example, in one embodiment, atthe end of each round of the game of Z Hot Dice, the player or playershaving receiving the highest points for the last round and playershaving the highest total points for rounds may be displayed to otherplayers. In this manner, a player may compare their total points tothose of other players for determining where they stand in an attempt towin the game against the other players.

In one or more embodiments, the multiple players may play against thehouse, such as a computer generated game result. In one such embodimentas implemented to the game of Z Hot Dice, the controller may play a gameand generate results of spins, fill categories and achieve point totalsassociated with those categories and total points. In one embodiment,prizes or awards may be provided to a player who obtains a greater totalof points than the house. The size of the prize awarded may depend onthe number of players who are successful in beating the house. In thisembodiment, the house's dice hands and the house point totals may bedisplayed to all players for their observation.

The multi-player game of the invention has many unique aspects andadvantages. First, a multi-player game is provided. As is known, currentgaming devices are arranged to be played by single players against thehouse, lending to a very solitary form of play. In accordance with theinvention, there is provided a method of presenting a game on a gamingdevice which is associated with many other players. A player of thegaming device feels attached or associated with these other players,even though they may be located remote from one another. Of course, inone or more embodiments, a plurality of gaming devices may be locatedadjacent one another, whereby players located in close proximity to oneanother all participate in the same game, lending to substantialcomradery and interaction.

In accordance with the invention there is provided a multi-player gamewhere each player's luck and/or skill in playing an event of the game isoutcome determinative as to the overall game. In one embodiment, eachplayer is in competition with the others, attempting to gain a highestscore or other result which entitles them to be declared a winner of thegame. In another embodiment, each player is in competition with thehouse, attempting to beat the house and be declared a winner.Regardless, a player's decisions, such as which dice to hold, dictate inpart the outcome of the game for the player.

As used herein, the term “computer-controlled slot machine” denotes acomputer controlled machine which facilitates wagering, which generallyrequires the input of money in order to be operated, and which outputsmoney in response to the achievement of winning wagering results. Itwill be appreciated that one or more aspects of the machine, includingthe interface or what is referred to herein as the touch sensitivedisplay may be electrical, mechanical and/or electro-mechanical innature. For example, while the buttons may comprise touch-sensitiveareas of a display, they may comprise electro-mechanical buttons whichare activated by mechanical movement (such as depression) by a player.In addition, the simulated dice may, instead of comprising solelycomputer generated images, actually comprise dice or dice faces mountedon a rotating reel and arranged to stop in controlled positions. Thesimulated dice or other symbols may be provided in a variety of othermanners, such as by laser light generation. The dice or other symbolsare referred to in certain instances as “simulated,” but could actuallycomprise faces of actual physical dice. The displays and display areasmay comprise CRT type displays, LCD or LED displays or any other meansfor displaying information now known or later developed.

Of course, the present invention is not limited to the generation anddisplay of images in the form of the video simulated dice. In otherembodiments, other images are generated and displayed in the course ofgame play. For example, in one embodiment, the images generated anddisplayed are in the form of different colors. In another embodiment,graphical representations of different types of fruit are generated anddisplayed. In yet another embodiment, roman numerals are utilized. Thegeneration and subsequent display of any image in a set of at least twodisplay areas in the course of game play is within the scope of thepresent invention.

It will be appreciated that various features of the present inventionmay be applied to existing games or games later developed. For example,the feature of permitting a player to “pause” a game and then continuethe game at one or one of several gaming machines may be applied topresent or future games. For example, the pause feature may be appliedto video poker games or the like. Likewise, the feature of havingbonuses associated with more than one event and/or cumulative bonusesmay be applied to present or future games. For example, a typical slotmachine may be configured to include particular winning combinationswhich, when received by a player, entitle the player to a first bonus.Additional bonuses may be won by receiving other combinations, and atotal bonus may be awarded for receiving yet another specialcombination.

Another feature which may be applied to the games of the inventioninvolves the duplication of displayed dice or symbols after a spin intoadditional “hands.” For example, after a first spin, a player may electto hold a target number which is displayed three times (i.e. a 3 of aKind). These same symbols may then be displayed in one or moreadditional rows or hands. The player may then be permitted to spinagain, in an attempt to achieve a winning combination in any or all ofthe hands or rows. In the example given, either 2 or 3 additionalsymbols (depending on whether each row had a maximum of 5 or 6 symbols)would be displayed randomly to fill each row. The combination of thenewly displayed symbols and the three originally held symbols would thenbe evaluated to determine if the player had won. The player may beawarded a payout for each winning row, or only for rows for which theplayer placed a wager. Alternatively, the player might be permitted toretain the highest winning combination from the several rows fordetermining the payout to be awarded in the column for that targetnumber.

In one or more embodiments of the invention, such as illustrated in FIG.6, a gaming machine in accordance with the invention may include arandom number generator. The random number generator is adapted toproduce random numbers which represent the outcome of the rolls of thedice or other symbols. For example, the numbers 1 2 4 3 5 5 may berandomly generated representing the outcome of a roll of six dice. Thesenumbers may correspond to the side of the die bearing the symbols 1 2 43 5 5.

In another embodiment of the invention, permutations of roll outcomesare stored in a memory. One of the permutations is selected in order todetermine the outcome of a roll. In one embodiment, the selection israndom. In one embodiment, particular permutations may be removeddepending on the status of the game. For example, if a player has playedthe target number 2, then all permutations containing the number 2 maybe removed from selection. In one embodiment, the permutations may beassociated with registers or memory locations. Selections of outcomesmay then be made from memory locations. For example, permutations ofoutcomes without 2's may be located in one memory location, and outcomeswithout 3's may be located in another memory location.

Another embodiment of a game in accordance with the invention will bedescribed with reference where applicable to FIG. 17. This game isreferred to herein as the game of Zingo.

FIG. 17 illustrates a touch sensitive display 1715 for implementing thegame of Zingo. A first area 1716 of the display 1715 is arranged todisplay a set of symbols or indicia. In one embodiment, the symbolscomprise the sides of a dice. A second area 1718 of the display 1715 isarranged to display one or more combinations of player symbols. Thedisplayed symbols preferably comprise combinations of the symbols whichmay be displayed in the first area 1716. In one embodiment, thecombinations of player symbols are arranged into lines or rows 1720,each line or row having the same number of positions for display ofsymbols as may be displayed in the first area. As illustrated, sixpositions are provided in the first area 1716 for displaying acombination of six symbols. Preferably, the second area 1718 is thusarranged to display rows of six symbols as well.

As described in more detail below, as one object of the invention, aplayer attempts to match as many of the symbols in the second area 1718with symbols which are displayed in the first area 1716. The symbolsdisplayed in the first area 1716 may be referred to as the game, house,post, called or other symbols, as such symbols form a set of symbolsover which the player has no control but attempts utilize to match theirsymbols in the second area 1718. As detailed below, in one embodiment,these symbols change during the course of a game. The symbols in thesecond area 1718 may be referred to as the player's symbols, main orother symbols. As detailed below, in one embodiment, these symbolsremain the same during the course of a game.

As stated, the symbols which may be displayed in either area preferablycomprise each side or face of a dice. Thus, each position of first area1716 is capable of displaying each of the six sides of a dice. In otherembodiments of the invention, other symbols may be displayed. Forexample, as detailed above in conjunction with the description of othergames herein, the symbols or indicia may comprise pictures of fruit,letters, numbers or representations of other elements/items. The symbolsmay be distinguished by color (such as red, white and blue as describedabove) or in other manners. The total number of different symbols whichmay be displayed at each position is preferably at least two, and may bemore or less than 6. In one embodiment, the number of symbols which maybe displayed at each position may vary from another position.

Preferably, the number of positions of symbols in each row or line 1720of symbols displayed in the second area 1718 is the same as the numberof positions of symbols in the first area 1716. This number of positionsmay comprise 6, but may also comprise less than six or more than six. Ina preferred embodiment, 6 positions are chosen when the symbols to bedisplayed comprise combinations of the 6 sides of a dice.

In one embodiment of the invention, a plurality of combinations ofsymbols are displayed in the second area 1718. In the embodimentillustrated, six rows 1720 of symbol combinations are displayed.Preferably, each row displays a different combination of symbols.

A method of playing a game will now be described with reference to FIG.17. In one embodiment, the game is arranged as a wager-type game inwhich a player is required to “buy-in” to the game, such as by placing abet. When the game is presented on a display 1715, the display may beassociated with a gaming machine including a wager-accepting device,such as a coin or bill acceptor. As described below, the player need notprovide payment in this form or at the time the game starts. Forexample, when playing a “paper” version of the game, the player maypurchase a game card on which player indicia are printed.

In accordance with one embodiment of the invention, the method thusincludes the step of a player placing a wager or otherwise establishingentitlement to play the game. In a next step, a combination of symbolsis displayed in the first area 1716. In a preferred embodiment, thesymbols which are displayed are selected randomly. The symbols displayedin the first area 1716 are compared to the symbols displayed in thefirst row in the second area 1718. If any of the symbols are the same,in one embodiment, a “match” is declared. In the preferred embodiment, amatch only occurs if the symbol which is displayed in the first area1716 is the same as and in the same position as the symbol displayed inthe second area 1718.

In one embodiment, if a match results, then the symbol in the row in thesecond area 1718 is highlighted or another indication is provided to theplayer of the match. In one embodiment, the indication of match occursby a computer comparing the displayed symbols. In another embodiment,the player is required to provide input for a match, such as by pressinga “hold” button associated with the position or touching the area of thedisplay where the symbol is displayed.

In the preferred embodiment of the invention, a player receives a scoreassociated with a match. In one embodiment, the score comprises pointsor another numerical value. In one embodiment, the points comprise thepoints of the matched dice. The player's score associated with aparticular row is displayed on the display 1715.

In a preferred embodiment, a player has three opportunities to match thesymbols displayed in a row of the second area 1718 with symbolsdisplayed in the first area 1716. Thus, in a next step, a new or nextset of symbols is displayed in the first area 1716. Each display of anew set or combination of symbols in the first area 1716 may be referredto as a “roll” or “spin.” After the second spin or roll, the symbolsdisplayed in the first area 1716 are compared to those displayed in thesame row of the second area 1718, and matches are determined. In apreferred embodiment, once a symbol in the row of the second area 1718has been matched, it does not need to be matched again during laterspins or rolls. A player attempts to match each of the symbols in therow with a symbol displayed in the first area 1716 at least once duringthe course of the three (or other number) of rolls. If new matchesresult from the second spin or roll, then the player's score is updated.A new (i.e. third) spin or roll is initiated. The resulting displayedsymbols are again compared.

In one embodiment, a round of play comprises the display of one or moresets of symbols in the first area 1716 for comparison with the symbolsdisplayed in the second area 1718. In a preferred embodiment, during around three sets of symbols displayed in the first area 1716 arecompared against symbols in the second area 1718. The player's total forthe round may then be used to determine if the player is a winner of thegame, such as for entitlement to an award.

In a preferred embodiment, as illustrated in FIG. 17, however, the gameincludes more than one round. In one embodiment, the number of rounds isdependent upon the number of groupings of symbols in the second area1718 to which symbols are compared from the first area 1716. In eachround, the game continues in similar fashion to that described aboveuntil the player has completed play with respect to each row orcombination of symbols in the second area 1718. In the embodimentillustrated, as a result of the play of the first round, the playermatched the dice symbols 2, 6, 4, 5, 3 during one or more of the rollsor spins of the symbols in the first area 1716. This resulted in aplayer receiving 20 points: the sum of the faces of the dice. In thesecond round, the player matched the dice symbols 5, 2, 6 for a score of13.

In a preferred embodiment, the display 1715 is arranged to display aplayer's score for each row and, in one or more embodiments, any bonusreceived. In one embodiment, in similar fashion to the game of Draw Dicepreviously described, a player may receive a bonus score for matching atleast a specified minimum number of the symbols, or a specified minimumnumber of symbols upon the first or by the second roll or spin. Forexample, a player may be awarded a 50 point bonus for matching fivesymbols upon the first spin, as illustrated in FIG. 17.

In a preferred embodiment, the display 1715 displays a total scorecomprising the sum of the score for each row and the bonus (if any) foreach row.

In one embodiment, a player is rewarded an award or declared a winnerbased upon the player's score. A player may be declared a winner if theplayer's score is greater than a predetermined score. In anotherembodiment, the player may be declared a winner based upon the player'sscore as compared to the scores of other players or the house.

In one or more embodiments, the game is implemented as a multi-playergame. In one embodiment, the players may play the game at the same ordifferent times, and one or more players may be awarded winnings as theend of a predetermined time. Such an arrangement is described above,wherein the players achieving the highest scores during a predeterminedperiod of time, such as a week, may be declared winners. In anotherembodiment, the game may be played by several players simultaneously,such as described above.

In the multi-player version of the game it is preferred that each playerhave the opportunity to obtain the same highest score. On the otherhand, it is preferred that the players not play the exact same form ofthe game when playing the game simultaneously, since each players gameoutcome would be the same. In an embodiment such as illustrated in FIG.17, it is desired that each player play a game in which the symbolsdisplayed in the second area have the same point total, but comprisedifferent combinations of symbols. In the embodiment illustrated where amatrix of 6 rows of 6 symbols (i.e. 36 symbols) of sides of dice aredisplayed, the sum of the faces may comprise 126. In that event, thereare over 1000 different combinations of symbols which may be displayedin the matrix, such that at least one thousand players may play the gameat the same time using a unique combination of symbols. Of course, agreater or lesser number of combinations may result when a greater orlesser number of symbols is used.

The game in principal may be played in a variety of formats andincluding a variety of options. In one embodiment, the spun or rolledsymbols need not be displayed on the same display as the player'ssymbols. For example, the outcome of a roll or spin may be displayed onanother device or in another area, such as on a separate monitor orprojector. In one embodiment, the game may be implemented in a slotmachine type format including reels, where the reels display the symbolsand the reels rotate to represent each spin or roll. The spinning of thereels may be initiated remotely, and in a multi-player game format, asignal may be sent to each machine causing the reels to rotate and allstop in the same position.

In one embodiment, the player's symbols may be displayed in a mannerother than by a touch-sensitive or other video type display. Forexample, the symbols may be associated with reels as well. At thebeginning of a game, the reels may all rotate and stop to display thematrix of indicia which comprise the symbols of the second area. Inanother embodiment, the symbols may be printed on cards or similarmembers. In such event, the outcome of the game may require manualconfirmation of the matches.

In one embodiment the player's symbols need not comprise a matrix ofsymbols. Instead, the symbols may be arranged in a variety of fashions,such as an X or T or the like. In this embodiment, instead or inaddition to providing a score for matched symbols, the goal may be toattempt to match each and every symbol of the configuration. The winnerof the game may be each or every player who matches all of the symbolsof the pattern.

The combinations of symbols may also be arranged in vertical columns.Not all of the symbols need to be displayed at the same time. Forexample, in one embodiment a first row of symbols may be displayed andthe other five rows of symbols may remain blank until the successiverounds of the game progress.

In one embodiment, a player may be provided a bonus score or award ifthe player receives a predetermined pattern of symbols from a group ofsymbols. For example, while playing a game comprising a matrix of 36symbols, a player may be provided a bonus score or award for matchingthe symbols forming an X through the matrix.

In one or more embodiments, bonuses or other events and awards may beprovided, including one or more of the bonus events described above. Forexample, with reference to the embodiment illustrated in FIG. 17, aplayer may be provided a bonus score or award if the player matches atleast 4 symbols of each of the 6 rows. A player may be awarded a bonusscore or award for matching every symbol.

In one embodiment, a player may be permitted to play one or more wildcards. The wildcards may be placed anywhere in the combination of playersymbols and constitutes an automatic match, regardless of whether thesymbol is actually matched during play of the game. Preferably, theplayer must indicate the location of the wildcard(s) before play of thegame begins.

The game of the invention is particular suited to the multi-player gameformat described above where the timing of certain aspects or events ofplay is controlled. In this arrangement, all players are provided a setof player symbols. A single set of symbols is displayed to all playersfor comparison of a match.

In one embodiment of the invention, a match may be declared if a symboldisplayed in the first area matches a symbol of a row in the secondarea, regardless of whether the matching symbols are displayed in thesame position. For example, referred to FIG. 17, if at the beginning ofthe game the first set of symbols were as displayed, the player would bepermitted a match for the display of the 2 in the first position of thefirst set of symbols with the 2 in the first row of the second set ofsymbols.

In another embodiment, a player may be permitted to declare a match whenany symbol which is displayed in the first area matches any symboldisplayed in the second area. In one embodiment, a player may use adisplayed symbol in the first area only once. The game may comprise therolling or display of a predetermined number of sets of first symbols.The player attempts to match as may of the symbols in the second set aspossible. In one embodiment, a player may attempt to match every symbolin the second set in order to win. In another embodiment, the player maybe provided a score comprising the sum of the matched symbol values.

In the event the game comprises matching symbols regardless of position,the symbols which are displayed in the first area need not be arrangedsimilar to those in the second area. For example, a single symbol, pairof symbols or the like may be displayed and used by the players inmatching to the symbols in the player area.

In one embodiment, the score may comprise other than the sum of the dicevalue. For example, in the event symbols such as fruit are utilized,each symbol may have an associated value. The value for each symbol mayremain the same or change based on criteria such as the row in which thesymbol is located.

It will be understood that the above described arrangements of apparatusand the method therefrom are merely illustrative of applications of theprinciples of this invention and many other embodiments andmodifications may be made without departing from the spirit and scope ofthe invention as defined in the claims.
